Extracts from transgenic rice plants could help stop the spread of HIV, according to research results from an international effort that included an Iowa State University scientist. Raziel Antonio-Ordonez, a postdoctoral researcher in agronomy, contributed to a research team that successfully developed a transgenic rice plant that expresses three different proteins that can stop human immunodeficiency virus (HIV) from entering human cells. The finding could lead to a less costly, easier way of producing prophylactics that could stop the spread of HIV, particularly in the developing world. The peer-reviewed academic journal Proceedings of the National Academy of Sciences published the research findings, available here.
